OTIS R. NICKERSON, OF DREXEL, MISSOURI CATTLE-PUMP.

Specification of Letters Patent. Application filed July 31, 1911.

Patented Aug. 5,1913. Serial No. 641,502.

To all whom it may concern:

Be it known that I, OTIs R. NIoKERsoN, a citizen of the United States, residing at Drexel, in the county of' Cass, State of Missouri, have invented certain new and useful Improvements in Cattle-Pumps; and I do hereby'declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to' which it appertains to make and use the same.

' This invention relates to pumps and more especially to those commonly termed cattle pumps and the object of the invention is to provide a novel 'p' mping apparatus of this character in whic the water is raised from a well or cistern from air pressure created exterior of the well upon the approach of the stock to a water tank in connection with which the device operates.

A still further object of the invention is i to provide an air tank adapted to receive 'air under pressure from a pump operated from a revolving platform upon which the stock ap roaches the tank so that the water will be ifted by the air in a siphon action. A still further object of the invention is to provide. means which will permit the escape of the air from the tank after the water 80 tank has been filled so that continued operation of the pump will not cause the water tank to overflow.

With these and other objects in view, the invention consists of certain other combinations and arrangements of parts as will be hereinafter more fully described and claimed, it being a still further object to provide a device which will not be likely to t out of working order. fifths drawings :Figure 1 is avertical sectional view of a well or cistern with my improved cattle ump in elevation and applied thereto; Fig. 2 is a plan view thereof. Fig. 3 is a longitudinal sectional view of the revolving platform. Fig. 4 is a transverse sectional view thereof. Fig. 5 is a detail .sectional view of the air tank and pump connected thereto, to more clearly illustrate the relief valve therein for permitting the escape of the air when the water tank is full and the pumpis operated in the usual manner. Fig. 6 is a detail sectional view showing the use of a float valve to automatically control the discharge of air 55 from the air cylinder for raising the water.

Referring to the accompanying drawthere is shown a well or cistern 1O lugs, which is provided with a top 11 adapted to receive an approximately U-shaped pipe structure having a supply portion 12 and anoutlet portion 13, the bight portion 14 of the pipe; terminating above the bottom of the well a short distance and extending into the water therein. Positioned slightly above the port-ion let and 5 suitably secured to and communicating with the outlet portion 13 is an entrance connection 15,-comprising an angular section of pipe having its horizontal portion secured to the section 13 and its vertical portion extending downwardlv to permit the proper entrance of water into the outlet portion. This portion 13 of the pipe structure terminates in a spout 16 adapted to discharge the Water into a tank 17 which is preferably circular in -form and from which the stock are adapted to be watered in the usual manner. In order to supply water to the tank 17, the upper end of, the pipe connection or supply pipe 12 terminates below the upper end of the discharge or outlet pipe 13 and is extended in a horizontal position as shown at 18 and connected to the upper end of an air tank 19, said air tank being positioned at any convenient pointadjacent to the water tank 17 and has a pipe connection 20 with a pump cylinder 21 suitably supported adjacent the lower end of the tank 19. This pump cylinder 21 has a piston 22 working therein and its piston rod 23 operates through one end of the cyliner and is eccentrically connected as shown at 24 to a crank disk 25.

In order to operate the pump I provide a revolving platform which is supported in an inclined position adjacent to the Water tank and is suitably guarded if desired so that the cattle or stock must approach the tank upon the platform,in order to drink. This platform comprises a series of angle bars 26 extending longitudinally of the platform and secured together at their ends, the said bars being spaced apart vertically and supported at their uppermost ends by uprights 28 while the lower ends of the bars are also spaced from the ground by uprights 29. The angle bars 26 are located adjacent the ends and central portions of the platform and the ends therof are extended inwardly as shown at 30 to rotatably receive a pair of shafts 31 and upon which a series of sprocket wheels 32 are mounted preferably three at each end of the platform adjacent to the angle" bars. Endless chains 33 are trained around said sprocket wheels and are secured together for simultaneous rotation by a plurality of transverse tread strips 34 which are secured to eachof the chains. One of the uppermost uprights 28 of the platform rotatably carries the crank disk 25 adjacent its lower portion for the proper attachment of a pitman rod 23 which is con nected to the piston and said crank disk has an endless chain 25 passed around-it and the adjacent sprocket Wheel 32 disposed thereabove, whereby when the animals approach the tank upon the platform, said platform will revolve causing the disk to rotate and operate the pump to supply. air under pressure to the air tank.

A valve 35 is mounted upon the horizontal portion 18 of the air supply pipe 12 so as to control the passage of air from the air tank when created as above described, it being understood that when this valve is closed, the pump will be operative and in order to permit the escape of air from the air tank when the said valve is closed or the water tank is full, I provide an automatically actuated release valve 36 in the top of a the air tank so as to open when the air within the tank has reached a predetermined pressure. -lVhen the valve 36 is open and the pump is operated, air will be forced through the supply pipe 12 and in passing out the pipe 13 will create a suction or siphon to draw water through the entrance connection 15 and discharge the same through the spout 16 into the water tank, it being understood that this operation takes place each time the platform is revolved by the approach of the stock to the water tank.

If desired, the entrance opening of the connection 15 may be provided with a suitable filter member 37 so as to purify the water in entering the discharge connection, and it will be evident from the foregoing description in connection with the accompanying drawings that I have provided an improved and durable form of pump which will be positive in operation in the manner specified. The pump may be constructed and applied to wells or other common sources of water supply, thereby rendering the same universal in use.

The release or relief valve 36 comprises a short pipe section 38 secured to the top of the air tank 19 by means of a flanged portion 10 and is provided with a diametrically arranged spider bar a1 adapted to receive the upper end of a valve stem 12 for vertical movement therein but to provide sufficient opening for the escape of the air from the tank upon opposite sides thereof, when it exceeds a predetermined pressure. A valve head 13 is carried at the lower end of the stem 42 and operates in a seat 14 formed as an opening in the top of the tank 19' and said head is held in a seated position by means of a coiled spring 15 which is disposed between the bar 41' and a collar 46 upon the stem so as to normally exert downward pressure upon the valve, it being understood that the said spring may be regulated to permit opening of the valve to any desired pressure for the successful operation of the device.

I also provide the pump cylinder with an inwardly opening flap valve 17 to admit air to the cylinder on the suction Stroke of the piston 22, and the pipe connection 20 is provided with a. flap valve 48 mounted within the air tank 19 to permit the forcing of air into the said tank but prevent back pressure upon the piston from the air within the air tank.

As shown in Fig. 6 of the drawings, I provide means for automatically supplying air from the air tank to the pipe 18 and also to prevent the escape thereof when the water tank is full and for this purpose I provide a float 49 which is supported upon the water within the water tank 17 provided with a vertical standard 50 having a downturned end 51, the portion 50 being slidable in a guideway carried by the water tank to close the valve 52 when the tank is full and to permit opening of the valve through the medium of a spring arm 53 carried by the air tank, when the water falls below a certain level and thus permit water to be automatically supplied to the tank at all times.
